             Summary: Many builds encountering starvation on Jenkins
                 Key: INFRA-6177
                 URL: https://issues.apache.org/jira/browse/INFRA-6177
             Project: Infrastructure
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: Jenkins
            Reporter: Rob Vesse


I've noticed that lately there seems to be an increasing amount of build starvation happening on Jenkins, from what I can glean by what I can see of the build queue this is down to two main issues:

1 - General lack of slaves for generic tags
2 - Builds running ridiculously long and monopolizing resources

For example for builds tagged ubuntu there should be 6 servers (ubuntu1-ubuntu6) but right now only ubuntu4 and ubuntu6 are running

In terms of long running builds there is one in particular I always seem to see hogging resources (https://builds.apache.org/job/Qpid-Java-Java-MMS-TestMatrix/) which when it succeeds takes 22 hours to run which seems excessive.

While I appreciate the ASF has limited build and infrastructure resources having the build servers up more reliably and addressing excessively long builds (whether by talking to the responsible projects or by imposing some limit on build time) would go a long way to making things smoother for Apache developers.
